Zed's DeltaDB Rebuilds Version Control Around Operations, Not Commits

DeltaDB records every operation between commits and gives each one a stable identity, using conflict-free replicated worktrees so multiple humans and agents can edit the same files simultaneously across machines. Because references anchor to deltas rather than line numbers, permalinks survive refactors — and the conversation that produced a piece of code stays attached to it, retrievable by whoever, or whatever, reads that code next. Zed positions it as complementary to Git rather than a replacement: Git and CI keep running checks and connecting to the outside world. Beta is promised in a few weeks, currently waitlist-only, with open-source status and pricing unstated.
